In a remote control method, a virtual private network is established between a home control network key and a home control network device of the remote control system in a property. In order to establish the virtual private network both the home control network key and device determine their network paths to the Internet from the data transfer network to which they are connected. The determined network paths are stored in a home control network server on the Internet. When it is desired to form a virtual private network, the home control network server supplies the stored network paths to the home control network key and the home control network device. By utilizing the received network paths the home control network key and the home control network device start establishing a virtual private network between them with several known by them establishing methods of a data transfer connection.
